What’s snowballing? In XCOM, if your troops survive the mission, they get stronger, tougher and get more abilities, which makes them more likely to survive future missions and get tougher still. If they die, they’re replaced by vulnerable, weak rookies, who are likely to die and be replaced by vulnerable, weak rookies.

If you’re finding the game easy, it gets easier. If you’re finding the game hard, it gets harder.

And it’s not just theory-crafting, that’s exactly how my XCOM 2 campaign played out: early on we got crushed repeatedly, then a few lucky missions got us off the ground, and after that my people became almost unstoppable for 35 missions straight – even after I upped the game difficulty.

Any game with persistent resources will have some snowbally tendencies: success has to get you something, or failure has to cost you something, otherwise it’s not really persistent.
